Road-base is a well graded material, consisting of various sized particles containing coarse and fine aggregate, that when mixed and placed correctly enable compaction of the material into a layer that resists distortion due to weather cycles of wetting and drying as well as deformation due to vehicular mass and movement.
Road-base products, as the name suggests, are often used in the construction of road pavements; which are made up of several layers of material of varying property. Road-bases are generally classified into two main supply categories , as a “sub-base’ material and as a “base” material; which when placed at the correct moisture content and compactive effort, form rigid layers able to distribute traffic loading from the pavement surface to the ground beneath.
